It's not Brutus' fault. An entire generation was taught by
Mystery Science Theater 3000 that it's okay to talk during movies as long as you are making fun of it and the same goes for plays.
Things I like in today's strip: I love that the Thornapples are seeing a play based on the Stephen King novel
Rage where a high school student holds some of his fellow students hostage after shooting and killing two teachers. I also like the stylized "M" on the seat that Gladys is sitting in.
